本文的第一部分对微波辐射在有机合成中的应用进行了较为全面的文献综述。

By the end of 2005, its production capacity reached 330,000 T/Y urea, 300,000T/Y Synthetic Ammonia, 100,000T/Y sulfur compound fertilizer, 200,000T/Y hi-concentrated compound fertilizer, 80,000 T/Y vitriol, 30,000 T/Y muriatic acid, 50,000 T/Y carbinol and so on.

到2005年底，年生产规模已达到：合成氨30万吨，尿素33万吨，硫基复合肥10万吨，高浓度复合肥20万吨，硫酸8万吨，盐酸3万吨，甲醇5万吨、碳酸氢铵20万吨。

The 220 kt/a hydrogenation unit for FCC naphtha to reduce olefin and sulfur is evaluated in this paper.

阐述了220 kt/a催化裂化汽油加氢脱硫异构降烯烃装置的运行和标定情况。

The δ〓S value of pyrite, sphelerite and arsonopyrite is in the range of 4. 0‰ and -4. 2‰ with the highest frequency occurring around zero, indicating a uniformed sulfur source. The large variation and mainly negative values (0.2‰～-11. 3‰) of δ〓S for stibnite could be interpreted by isotope fractionation. The carbon isotopic characteristics exhibit a mixing nature of magmatic carbon and organic carbon.

矿床中的热液成因黄铁矿、闪锌矿和毒砂的δ〓S＝4.0‰—-4.2‰，呈塔式分布，δ〓S集中在0附近，表明其成矿体系具有均—化硫的同位素组成，而辉锑矿的δ〓S变化范围较大(0.2‰—-11.3‰)，除一个样品外均为负值，这是硫同位素分馏作用的结果。

The results indicated that most of the samples had acid producing potential, because of the high sulfur content or low acid neutralization capacity.

结果表明，大部分的样品都具有产酸潜力，这是因为它们较高的含硫量或较低的酸中和能力。

Sulfur and Phosphorus are low , the contents of Chronium and Nickle are at the

量控制得非常低，铬、镍含量控制在规定的中上限，这

" Niello: Black metallic alloy of sulfur with silver, copper , or lead, used to fill designs that have been engraved on the surface of a metal object, usually of silver."

黑金镶嵌：银、铜或铅的硫化黑色合金，用来镶嵌金属表面雕刻的图案。

The silver accessories nigrescence changes yellow is the normal natural phenomenon, because in the air and other natural medium's sulfur and the oxide compound and so on have certain corrosive action to the silver, after wearing period of time, will present some small spots, the long time will proliferate Large expanse, will turn the black.

银饰品变黑变黄是正常的自然现象，因空气和其它自然介质中的硫和氧化物等对银都有一定的腐蚀作用，在佩戴一段时间后，就会出现一些微小的斑点，久之会扩散成片，甚至变成黑色。

Later, people made up black gunpowder with niter, sulfur and charcoal of certain proportions on the basis of the formula.

后来，人们根据这个配方，将硝石、硫磺、木炭按一定比例配制在一起，制成了黑火药。

The compression set of nitrile rubber seal components are bad which is vulcanized with systems based on sulfur.

在橡胶密封件硫化体系中，由于硫磺硫化体系压缩永久变形性能比较差，而最常用的过氧化物交联剂过氧化二异丙苯的硫化胶容易产生刺鼻的异味，从而限制了它在高档制品中的用途。
